New SLAC-Stanford Battery Center Targets Energy Transition

The Department of Energy’s SLAC National Accelerator Laboratory and Stanford University announced the launch of a new joint battery center at SLAC. It will bring together the resources and expertise of the national lab, the university and Silicon Valley to accelerate the deployment of batteries and other energy storage solutions...

New Study Could Help Pinpoint Hidden Helium Gas Fields

Research led by the University of Oxford could help overturn the current supply crisis of helium, a vital societal resource. The study proposes a new model to account for the existence of previously unexplained helium-rich reservoirs. The findings, published in Nature, could help locate untapped reservoirs of accessible helium. Dr. Anran...

H2FLY Announces Liquid Hydrogen Filling Success

German-based H2FLY has announced success from a liquid hydrogen filling test of its HY4 hydrogen-electric aircraft. The on-ground test at Air Liquide’s Campus Technologies Grenoble in France saw liquid hydrogen fill the aircraft’s new liquid hydrogen storage system, designed and supplied by Air Liquide. Coming as a precursor to future tests in...

Delft Circuits Chosen by NASA JPL Scientist to Support BICEP Project in Antarctica

Delft Circuits announced its inclusion in the Background Imaging of Cosmic Extragalactic Polarization (BICEP) project in Antarctica, supporting NASA’s Jet Propulsion Laboratory at CalTech and other project partners. BICEP has been ongoing for several years and is now seeking solutions for a hardware upgrade to its telescope’s sensitivity as the...

Vulcan: Tanking tests performed on ULA’s new rocket

Completing the next phase of testing in preparation for the inaugural Vulcan rocket flight, the United Launch Alliance (ULA) team accomplished tanking demonstrations at Cape Canaveral Space Force Station, Florida. The pathfinder tests filled the Vulcan first stage and Centaur V upper stage with cryogenic propellant on separate days to validate...

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
